Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings. The structural diagram of the up-converter described in the embodiment of the present invention is as follows figure 1 As shown, it includes the following modules: a local oscillator frequency synthesizer, a quadrature modulator, a filter, a power automatic gain control module (AGC, Automatic gain control automatic volume control), a power attenuation module and a main control module.

[0030] 1. The local oscillator frequency synthesizer is used to generate frequency configuration information such as frequency division coefficient, frequency multiplication coefficient and working mode written by the main control module, based on the received frequency standard input signal, and generate various The local oscillator frequency of the frequency point is used to transmit the radio frequency local oscillator signal with the local oscillator frequency to the quadrature modul...

Abstract

The invention provides an up converter and a signal processing method thereof. The up converter mainly comprises a local frequency synthesizer, a quadrature modulator, a power automatic gain control module and a power attenuation module. The signal processing method mainly comprises: based on received frequency scale input signal and set frequency allocation data, the local frequency of various frequency points is generated, a radio frequency local signal having the local frequency and baseband signals of I and Q ways are mixed in the quadrature modulation mode to obtain a single side band radio frequency modulation signal; and the power of the single side band radio frequency modulation signal is subjected to automatic gain control, and then to accurate power control. The up converter can output the signals (such as navigation signal) compatible with a plurality of frequency points, and the frequency by which the signals are outputted can be conveniently changed in real time by a user during operation.

Description

technical field [0001] The invention relates to the field of electronic applications, in particular to an up-converter with real-time controllable output signal power and carrier frequency and a signal processing method thereof. Background technique [0002] Satellite navigation systems such as GPS (Global Position System, Global Positioning System), GLONASS (GLobal Orbiting NAvigation Satellite System, Global Orbiting Navigation Satellite System), GALI LEO (Galileo) and CNSS (Chinese Navigation Satellite System, China Navigation Satellite System) are used in military and Civilian fields have been increasingly widely used. Satellite navigation system-level test verification and receiver development and testing are inseparable from high-performance satellite navigation signal simulators. [0003] The satellite navigation signal simulator is a complex system combining simulation calculation software and signal generator hardware. The up-converter is an important component mod...
